BULB FOR AUTOMOBILE-HORNS AND THE LIKE.

To all whom it may concern:

Be it known that I, ALBERT CLnRnT, citizen of the French Republic,residing at Paris, Department of the Seine, in France, have inventedcertain new and useful Improvements in Bulbs for Automobile-Horns andthe Like; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The elastic bulbs of automobile horns and similar devices are usuallyapplied directly to the air pipe or body of the horn with the reducedconical portion of the bulb fitted directly over such pipe or horn. Thismethod of mounting the bulb presents the di'sadvan tage that the reducedconical portion of the bulb by means of which the attachment is eifectedwears out very quickly, and moreover, the formation of the bulb in asingle piece makes it necessary to introduce gas under pressure into theinterior of the bulb in molding the latter, whereby a uniform andhomogeneous molding of the bulb wall, to to give it the necessarystrength, is either made impossible, or, in any event, very diflicult.The shape of the usual one-piece bulb prevents the employment of a rigidone-piece core such as is necessary to produce an efficient molding ofthe bulb wall between two rigid mold walls subjected to high pressure.

The object of the present invention is to obviate these disadvantages;and the invention consists in constructing the bulb of two main parts,viz., an elastic body which can be molded on a solid core, and a rigidmember secured to said body and adapted to be applied to the air pipe orhorn body, all as hereinafter described and claimed.

The accompanying drawing shows in longitudinal section a bulbconstruction embodying the invention.

Referring to the drawing 1 designates a hollow elastic body of rubber orother suitable material, which is preferably of approximately sphericalshape and is provided with a relatively large open end portion or mouththrough which a solid core for molding the body may be easily removed.The open end portion or mouth of the body is preferably provided with alaterally directed bead 2 integral therewith, whereby the body may besecured to a rigid section 3 by means of which the bulb is mounted onits support.

Specification of Letters Patent.

Application filed. August 28, 1911.

Patented Dec. 12, 1911. Serial No. 846,539.

The rigid section 3 is preferably of approximately conical shape, asshown, and at the open, relatively wide end of the same it is providedwith means whereby it may be firmly secured to the adjacent mouthportion of the elastic body 1. At the smaller end of the section 3 thelatter is suitably fitted on the bulb support, such as the air pipe 7.In the embodiment shown in the drawing the wide end of the rigid section3 is provided with a. laterally directed flange 4 in which is fitted theannular flange 5 of a rigid ring 5, preferably constructed of suitablemetal, and the bead 2 of the elastic body or section 1 is so seatedagainst the flange 5 that the latter is interposed between said bead andthe flange at of the rigid section 3. In order to secure firmly theparts in the position just indicated, a suitable device such as a ring 6is associated with the flange 4, said ring being threaded on said flangeand overlapping the bead 2, so that by screwing up the ring 6 it ispossible to press the head 2 and the flange 5 of the ring 5 firmlyagainst the annular seat afforded by the flange 4. However, thisspecific means for interconnecting the sections 1 and 8 is not essentialto all aspects of the invention.

The ring 5 is extended into the elastic body or section within andbeyond the mouth of said body, in order to reinforce the body at theedge thereof, and for the further purpose of supporting the body to acertain extent from the interior. It is therefore impossible to bend theelastic body in a lateral direction sufliciently to exert an unduestrain on its connection with the rigid section of the bulb. It willalso be evident that the ring 5 prevents the elastic body from beingcollapsed at the point where it is connected with the rigid bulbsection.

Without limiting myself to the construction shown, I claim:

1. In a bulb such as described, the combination of a hollow elastic bodyhaving a relatively wide open end or mouth, and a rigid section securedto said body adjacent said open end or mouth and having a reduced endportion to fit over a suitable sup- )ort. 1 2. In a bulb such asdescribed, the combination of a hollow elastic body having an open endportion, and a rigid approximately conical section secured at one end tosaid body at the mouth of the latter.

3. A bulb such as described, comprising a hollow elastic section havingan open mouth at one end, and a rigid section having a wide end securedto said mouth and a narrow end to secure the bulb on a suitable support.

4. A bulb such as described, comprising a hollow elastic section havingan open mouth, a second section secured to said first section at saidmouth, and an internal support for one of said sections associated withthe connection between the same.

5. A bulb such as described, comprising a hollow elastic section, arigid section, means to connect said sections, and means associated withsaid connecting means to support the elastic section interiorly.

6. A bulb such as described, comprising a rigid section having a lateralflange at one end, a hollow elastic section having an open mouth and abead adjacent said mouth seated on said flange, and a detachable deviceto hold said bead against said flange.

In testimony whereof I affix my signature, in presence of two witnesses.
